Hi Tom, Thank you for this wonderfully erudite explanation! And thanks for suggesting a path forward. I have a somewhat related question, but I think I'll ask it on a new thread.

Hi Darrell,
You are trying to remote display Chimera from a Linux machine to a Mac using the XQuartz X11 window server. As you¹ve found out this doesn¹t work very well. Unfortunately X remote display hasn¹t worked very well with OpenGL for a decade or more. Basically the X client on your Linux machine isn¹t compatible with the X server on your Mac, even though there are standards and they should work. The graphics card on your Linux server is not relevant ‹ it is not used. The Linux machine will send OpenGL to your Mac and its graphics card and the Mac graphics driver will be used. The output of glxinfo run on the Linux machine indicates you have a NVIDIA GeForce 9400M graphics card on the Mac and the Linux machine is using Mesa for its OpenGL. It looks like your Linux Mesa (which is the software OpenGL library) is version 1.4 which is archaic. The Mac graphics driver is willing to run OpenGL 2.1. (The Mac is the ³server² and the Linux machine is the ³client² ‹ the server actually renders the graphics on its screen).
The only chance of success with this setup is to update your Linux Mesa to a modern version. I don¹t think it is likely to work, but there is a chance. Usually remote display from one linux machine to another will work, and probably from Mac to Mac will also work. But once you get different X/OpenGL implementations on the client and server some bugs cause them to be incompatible with each other.
None of what I said pertains to VirtualGL ‹ I don¹t know what that is or whether it could help.
Tom

Hello again,
I still have to try VirtualGL (as suggested on a previous thread). However, I want to share the following information:
I learned that the 60 fps I was getting on glxgears is likely due to Ubuntu having "sync" enabled by default, which means that glxgears always runs at about 60 fps. So let's ignore that bit of information.

My glxinfo (see below at "OpenGL renderer string") suggests that I have an NVIDIA graphics card installed. But "lspci -vnn | grep -i VGA" suggests that I have a simple Matrox graphics card:

Hi Chimera friends,
I want to run a graphics-enabled Chimera from a remote Ubuntu server. The Ubuntu server is quite beefy (and not virtualized), but it has a stock video card. When I run "glxgears", I can see the gears and get about 60 fps (reported), but the gears don't move and aren't interactive.
I found this message from the listserv a few years ago that recommends the use of VirtualGL:
http://plato.cgl.ucsf.edu/pipermail/chimera-users/2012-September/007953. ht ml
My X windowing system is Xquartz on a Mac. Is my problem related to software GL or to the poor graphics card?
Related question: what X windowing system do you recommend on a Windows system? CYGWIN?
Thanks, Darrell
